Abstract
The utility model discloses a novel liquid resistance soft starting crossed rod type drive mechanism, which relates to the field of the soft starting of large and medium electromotors. The drive mechanism comprises a support assembly, a lift screw assembly and a guide track. The support assembly comprises a fixed support, a movable support, crossed rods and retractable pulley assemblies. Each retractable pulley assembly comprises a compression spring, an internal rod, an internal rod sleeve, an upper seat plate, a lower seat plate, a connecting rod and a guide pulley, and the retractable pulley assemblies are fixed on both ends of the movable support. When the guide track on both sides of a cabinet body is not welded in parallel, the retractable pulley assemblies can automatically adjust the extended or retracted distances of the guide pulleys, consequently, the guide pulleys can be kept in good contact with the guide track, the sticking and derailing phenomena which can easily occur on the conventional drive mechanism are prevented, and thereby the normal starting and stable operation of an electromotor are guaranteed.
Description
Technical field
The utility model relates to large and medium motor soft start field, relates in particular to a kind of novel liquid resistance soft start intersection single lever-type transmission mechanism.
Background technology
At present, what the pole plate transmission of liquid resistance soft starting cabinet was used is intersection single lever-type transmission mechanism, this transmission mechanism is by the rise and fall of single screw mandrel transmission control pole plate, its controlling party to leading block be fixed on the surplus type hole of channel-section steel of transmission mechanism, pulley is stuck in to slide up and down on the angle steel of cabinet both sides and fixes direction.But in the welding production process of cabinet both sides angle steel guide rail, occur both sides angle steel guide rail easily and weld uneven situation, both sides angle steel guide rail not parallel meeting causing transmission mechanism breaks down, the phenomenon that leading block is stuck and derail for example can occur, thereby have influence on the normal starting of motor.
The utility model content
For overcoming the deficiency on the prior art, the purpose of this utility model is to provide a kind of novel liquid resistance soft start intersection single lever-type transmission mechanism, this novel transmission mechanism can realize that leading block automatically adjusts flexible distance, eliminated the situation of the stuck and derailing of leading block.
In order to realize the purpose of this utility model, the technical solution of the utility model is as follows:
A kind of novel liquid resistance soft start intersection single lever-type transmission mechanism comprises groups of holders, elevating screw group and guide rail, and its groups of holders is made up of fixed support, travel(l)ing rest, crossbar and scalable assembly pulley.
Above-mentioned scalable assembly pulley is made up of stage clip, interior bar, interior bar cover, upper base plate, following seat board, connecting rod and leading block.
Above-mentioned scalable assembly pulley is fixed on the two ends of travel(l)ing rest.
In addition, the elevating screw group is made up of elevating screw and screw, guide rail by about two angle steel guide rails form.
This novel transmission mechanism combines groups of holders, elevating screw group and guide rail, leading block device in the groups of holders has been done improvement, stage clip and supporting construction have been increased, realize the automatic adjustment of the flexible distance of leading block thus, therefore, under the uneven situation of both sides angle steel guide rail, can accomplish that leading block is not stuck, do not derail, guaranteed the normal starting of motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of scalable assembly pulley.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As shown in Figure 1, fixed support 1 is arranged at this transmission mechanism top, the type of having a surplus above the fixed support 1 hole 9; Travel(l)ing rest 2 is arranged at the bottom, the type hole 9 of also having a surplus above the travel(l)ing rest 2, and travel(l)ing rest 2 two ends also are provided with scalable assembly pulley 10; There are two crossbars 3 at the middle part, and 5 connecting pins 8 are arranged above the crossbar 3; The middle part also has elevating screw 4 and screw 5, and screw 5 is arranged on the middle part of travel(l)ing rest 2; There are left hand corner steel guide rail 7 and right-hand corner steel guide rail 6 in both sides.
As shown in Figure 2, scalable assembly pulley 10 is fixed on the travel(l)ing rest 2, and the below contacts with right-hand corner steel guide rail 6 (or left hand corner steel guide rail 7); Scalable assembly pulley 10 comprises stage clip 16, interior bar 11, interior bar cover 12, upper base plate 15, following seat board 13, connecting rod 14 and leading block 17.
Its embodiment is:
Referring to Fig. 1, this novel liquid resistance soft start intersection single lever-type transmission mechanism comprises groups of holders, elevating screw group and guide rail, and its groups of holders is made up of fixed support 1, travel(l)ing rest 2, crossbar 3 and scalable assembly pulley 10.
Referring to Fig. 2, scalable assembly pulley 10 is made up of stage clip 16, interior bar 11, interior bar cover 12, upper base plate 15, following seat board 13, connecting rod 14 and leading block 17.Wherein interior bar 11 is welded on the middle of upper base plate 15, and upper base plate 15 is welded on above the travel(l)ing rest 2.Between interior bar 11 and the interior bar cover 12 is matched in clearance, and it is reciprocating that interior bar 11 overlaps 12 the insides at interior bar.
Above-mentioned scalable assembly pulley 10 is fixed on the two ends of travel(l)ing rest 2.
In addition, the elevating screw group is made up of elevating screw 4 and screw 5, when elevating screw 4 rotates, drives travel(l)ing rest 2 by screw 5 and does elevating movement.Guide rail is made up of left hand corner steel guide rail 7 and right-hand corner steel guide rail 6.
Connect with 1 connecting pin 8 between two crossbars 3, be connected with 2 connecting pins 8 respectively between two crossbars 3 and fixed support 1 and the travel(l)ing rest 2.
Since should be novel liquid resistance soft start intersection single lever-type transmission mechanism be provided with stage clip 16, so in the process moved on right-hand corner steel guide rail 6 (or left hand corner steel guide rail 7) of leading block 17, leading block 17 can remain with the good of guide rail and contact.When the distance between the guide rail became big, stage clip 16 was pushed leading block 17 to guide rail automatically by following seat board 13 and connecting rod 14 and is adjacent to it, thereby avoided the generation of derailment occurring; When the distance between the guide rail diminished, stage clip 16 was compressed, and interior bar cover 12 moves as straight line along interior bar 11, leading block 17 retreats, simultaneously because the spring force of stage clip 16, leading block 17 is kept and the contacting of guide rail, thereby avoid the generation of stuck phenomenon.
Basic principle of the present utility model, principal character and advantage have more than been described.We recognize that this utility model is by being provided with stage clip 16 parts such as grade by foregoing description, realized leading block 17 advance to contract automatically, guaranteed that situation stuck and derailing can not appear in leading block 17 under the uneven situation of guide rail, thereby ensured the normal starting of motor, improved operating efficiency.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the present utility model all be included in the utility model.
